STOVE Filed March 12, 1946 2 Sheets-Sheet 1 Patented Feb. 21, 1950 UNITED STATES PTENT FFICE 1 Claim.

This invention relates to stoves.

An object of this invention is to provide a stove which is light in weight and simple and inexpensive in construction, and which may be used permanently in one location or may be moved from location to location as desired.

Another object of this invention is to provide a stove which has novel features of construction enabling it to be quickly folded into a small total volume for carrying it from place to place, and then, upon arrival at the destination it can be just as quickly opened out into a self-supporting stove and broiler.

A further object of the invention is to provide a camp broiler and charcoal stove which folds up into a portable unit and opens up into a sturdy and efficient, self-supporting stove capable of burning charcoal or other inexpensive fuel.

Other objects and. advantages of the invention will become apparent from the following description of a preferred embodiment thereof, as illustrated in the accompanying drawings and in which- Figure 1 is a front elevational view of my improved stove set up ready for operation.

Figure 2 is a side elevation of the stove shown in Figure 1, as seen from the left side.

Figure 3 is a plan view partly in section of the stove, taken along line 3--3 of Figure l.

Figure 4 is partly fragmentary vertical section taken on line ffl- 4 of Figure 3.

Figure 5 is vertical section taken on line fl-d of Figure 3 but showing the position of the parts when folded up.

Figure 6 is a perspective detail View of the part hereinafter described as the fire hole plate.

As shown in the drawings, the stove has a body portion indicated generally at 2 and having four rectangular sideswhich may be referred to as the front member il, the rear member li, the left member 8, and the right member lll. The body portion may, if desired, be formed out of a single piece of sheet metal such as galvanized steel or iron, suitably bent to form the four sides, or it may be made of four separate pieces of sheet metal joined at the corners by angle irons or other means well known in the art. As best seen in Figures 4 and 5, the lower edges of the members 4, t, S and lil are preferably turned inward as at i2 and I4, and the upper edges oi the members are also turned inward as at id and l, for added stiffness and for purposes which will become apparent from the description to follow.

Handles and 22 are secured to side members 8 and lil respectively, and handle 2li is secured to front member l so the stove may be easily lifted and carried. Left and right leg members 26 and 28 are formed out of sheet me'tal of substantially the same width as side members 8 and Hi. The leg membersr have inturned edges as'at 3l), for added'stifness and strength, and are pivotally secured at one end to the lower corners of the stove body portion 2 by means of bolts 32 extending through holes in the inturned edges 3@ and through matching holes in the abutting sheet metal surfaces of front member i and rear memn ber ii. The lower edges of the leg members 26 and 2'53 are notched out at 33 and 3Q to form feet 36 'upon which the stove rests on ythe ground 38' or other level surface. The locations of the holes through which the pivot bolts 32 extend are so chosen as to allow the leg members 26 and 28 to open out as shownin Figure 1, with the lower ends of the leg members which rest on the ground being further apart than the upper pivoted ends of the leg members, thus affording increased stability for the stove, and in addition allowing the upper edges do and 'l2 of the leg members to bear against the lower margins of side mein-bers 8 and lll, to limit the opening out movement of the leg members substantially as shown.

When, as shown in Figure 5, the leg members are in closed position, they serve to close the otherwise open bottom of stove body portion 2, the left leg member 26 being rst pivoted 'about its pivot pins 32 in the direction indicated by dotted line i3 in Figure 1, and then right leg member 28 is pivoted about its pivot pins 32 in the direction indicated by dotted line 46 in Figure 1, so that they occupy the positions shown in Figure 5, with leg member 26 being almost wholly inside leg member 28. To accomplish this, it is obviously necessary that, as seen in Figure 3, the width of right leg member 28 be slightly greater than that of left leg member 2t.

The rire-box or lire-pit i8 has four downwardly converging side members, namely left and right sides 50 and 52, rear member 54, and a front member nearest front member 4 but not shown. The upper edges of the re pit are joined at 56 to the inner inturned edges of the side members 4, 6, t and l0 of the stove body portion, in any usual manner well known in the art. The bottom or grate 56, perforated with a plurality of holes 53, is substantially rectangular in plan, with its down-turned edges fill being joined to the corresponding lower edges of the side members of the fire-pit in any usual manner such as by means of rivets, the re-pit serving as the support for the burning charcoal, briquets or other fuel used, and

3 the perforations 58 serving to permit air to pass through to form a draft.

To prevent overheating the body portion, its inner surfaces are covered with sheet asbestos 62 or other insulating material which is applied to the inner surface in any manner well known in the art.

The inturned upper edges of the sides of stove body portion 2 thus form a top 64 with a substantially rectangular central aperture 65 in which is supported the nre-pit 48. A grill 66, substantially rectangular in shape and slightly larger than the fire aperture 65, and formed of a plurality of parallel wires or rods 68 joined at their ends by transverse wires or rods 69, is hinged at one edge 10 to the corresponding edge of body portion top 64 by hinges 12, thus permitting the grill to be tilted back on the hinges to clean out the re-pit or to add fuel to it. A rectangular hot plate 14, having down turned marginal edges 16 and being slightly larger than grill 66, is disposed over the grill as illustrated with the edges 16 resting on the stove top, the hot plate being provided with a circular opening 18 to permit direct heat to come up from the re-pit when desired, such as for toasting, or for boiling or coffee making. Or, with the hot plate removed, the entire grill surface may be used for broiling frankfurters or other meats.

The stove has a top closing cover 80 with depending marginal edges 82, the closing cover 80 being hinged at its rearward edge to the corresponding edge of the stove body by means of hinges 84, `a lock 86 of any suitable type being provided to hold the front edges of the stove body and the closing cover 80 together when the stove is closed with the cover 80 down.

Left and right windshield wings 83 and 90 formed of sheet metal have their inturned edges 9,2 and 94 hinged to the inner surface of closing cover 80 by means of hinges 96, so the wings are able to be turned in a vertical plane on the hinges when the cover 80 is open. The wings protect the top of the stove from side drafts, and also rest on the stove body `and thus furnish Support to keep the top closing cover 80 open. The wings are folded in the directions of the dotted lines 98 and 100 in Figure 3 to the relative positions indicated in Figure in order to close the top closing cover 80.

Although I have described a preferred embodiment of my invention in specific terms, it is to be understood that various changes may be made in the shape, size, materials, arrangement without departing from the spirit and scope of the invention as claimed.

I claim:

A portable and collapsible stove comprising a box-like main body and an inverted pan-shaped cover hinged to the back of said main body to swing upwardly from collapsed and covering relation to the top of said main body to a vertical open position, the top of said main body comprising inwardly directed flange means dening a repot opening, a firepot suspended from said fiange means within said repot opening, said box-like main body being open at its lower end, and leg plates hinged at their upper ends to the opposite ends of said main body near the lower corners thereof, the hinge axes of said leg plates being located to permit said leg plates to be swung laterally inwardly and upwardly into overlapping relation forming a closure for the open bottom of said main body, said leg plates normally occupying downwardly and laterally outwardly angulated positions in which portions thereof above their hinge axes engage the ends of said main body with the lower ends of said leg plates engaging the ground to support said main body above the ground.
